'Ink horn' in the Bible
And, behold, six men came from the way of the higher gate, which lieth toward the north, and every man a slaughter weapon in his hand; and one man among them was clothed with linen, with a writer's inkhorn by his side: and they went in, and stood beside the brasen altar.
And the glory of the God of Israel was gone up from the cherub, whereupon he was, to the threshold of the house. And he called to the man clothed with linen, which had the writer's inkhorn by his side;
And He calleth unto the man who is clothed with linen, who hath the scribe's inkhorn at his loins, and Jehovah saith unto him, 'Pass on into the midst of the city, into the midst of Jerusalem, and thou hast made a mark on the foreheads of the men who are sighing and who are groaning for all the abominations that are done in its midst.'
